from the information i received OFSAA isnt solely to blame. the rules involved from the US stem from state and tournament sanctions by NFHS (National Federation of State High Schools Associations).
OFSAA is the ONLY governing body of sports in high school for Ontario with NFHS. If OSBA wants to apply to NFHS, then by all means. I was quick to point out the lack or personal attack by OFSAA on twitter but they cant be blamed entirely. So if a convenor from a tournament calls OFSAA to verify a team is sanctioned they will say no, not because of hindering athletes, but its actually a no. But what raises red flags is #1 why didnt this happen last yr and #2 did a convenor call OFSAA or did OFSAA call them??
Also I heard prep teams playing US high schools is the issue, whereas, playing prep isnt an issue. I personally dont know or have facts, only hearsay.
When it comes to issues with transfers within OFSAA I believe there is a very thin line that many cross with out red flags, while others get wrapped in red tape.
Girl transfers across the GTA one side to the other, moved, appealed 1 yr ban. Kid moves but stays within region and is eligible, where as another does, ineligible. Far too much hypocrisy in Ontario for high school basketball. Cant even imagine the BS involved with hockey.
OSFAA doesnt have to adapt to the new way or prep. OSBA and NPA have to apply to the NFHS. Teams like St Mikes, Vaughan and FHC are probably approved by OFSAA/NFHS to play because their schools have been part of it, whereas Lincoln, TRC, AI Academy arent.
Just my 2 cents from what I have been told.
